RATCHET-WRENCH.

SPECIFICATION forming part of Letters Patent No. 643,098, dated February 13, 1900.

Application led November 29 1399. Serial llo-738,706. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, WILLIAM M. ARTHUR,

a citizen of the United States, residing at Leadville, in the county of Lake and State of Colorado, have invented a new and useful Ratchet-Wrench, of which the following is a specification.

This invention relates to ratchet-wrenches, and has for its object to provide certain new and useful improvements whereby an ordinary spanner-wrench or a monkey-wrench may be equipped with an operating ratchethandle. It is, furthermore, designed to accommodate a single ratchet-handle to a plurality of wrenches without changingthe latter and without impairing their usefulness in their ordinary capacity."

With these and other objects in view the present invention consists in the combinationl and arrangement of parts as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective view illustrating the application of the present invention to an ordinary Spanner-wrench. Fig. 2 is a plan view of a monkey-wrench having the improved ratchet-handle applied thereto. Fig. 3 is a transverse sectional view taken through the connection between the ratchet-handle and the wrench. Fig. 4 is a detail perspective view of the detachable seat for the reception of the shank of the wrench.

Corresponding parts in the several figures of the drawings are designated by like characters of reference.

In carrying out my invention I provide a suitable handle l, having a laterally-enlarged head 2, the outer end of which is provided with a longitudinal bifurcation 3. Mounted to turn within this bifurcation is a ratchetdisk 4:, which is engaged byone or more dogs 5, pivoted within thev bifurcation 3, so as to control the operation of the ratchet-disk in opposite directions in any common or ordinary manner.

Projecting centrally from the ratchet-disk and extending a suitable distance at one side of the head 2 is a hub or stem 6, which turns with the disk. Adjacent to the exterior of the head 2 the hub or stem is provided with opposite shoulders 7, and outwardly from these shoulders the stem is made angular, as at 8, while the extremity thereof is screwthreaded.

Detachably fitted to the stem is a seat 9, which is provided with a central angular opening 10 for the reception of the angular portion of the stem, so that the seat may be supported upon the shoulders 7. At opposite ends of the seat there are provided the outwardlyprojecting iianges .or jaws l1.

To apply the ratchet-handle to a Spannerwrench l2, as shown in Fig. 1 of the drawings, the shank 13 is provided with an angular opening 14 for the reception of the angular portion 8 of the stern orhub so that said shank may rest flat upon the seat and snugly between the jaws or anges thereof, whereby the wrench is connected to the ratchet-disk, so as to be movable therewith. Fitted upon the threaded end of the stem is a suitable nut 15, adapted to bind upon the outer side of the shank 13, so as to prevent accidental displacement thereof.

In applying the handle to a monkeywrench, as indicated in Fig. 2 of the drawings, the handle is removed from the shank, and the latter is provided with an angular opening, so as to receive the angular portion of the stem 6, whereby the wrench is connected to the ratchet-disk, as hereinbefore described for the Spanner-wrench.

From the foregoing description it will be apparent that the seat 9 is removable from the stem 6, and it is designed to provide a plurality of seats of different sizes and shapes, so as to accommodate a single handle to a pluralitj1 of wrenches.

What I claim is- 1. In a ratchet-wrench, the combination of a handle, having a ratchet-disk, and dogs therefor, a central stem or hub carried by and movable with the disk, projecting at one side of the handle, and having an angular portion, a seat having an angular opening detachably fitting the angular portion of the stein, and a ICO Wrench having an angular opening receiving the angular portion of the stem, and also detaohably held Within the seat.

2. In a ratchet-Wrench, the combination with a handle, having a ratchet-disk, and dogs therefor, of a central stem or hub carried by and movable with the disk, projecting at one side of the handle, and provided with a shoulder, a seat detachably fitted to the stem and supported upon the shoulder, anda Wrench detachably held Within the seat.

3. In a ratchet-Wrench, the combination of a handle, having a ratchet-disk, and dogs therefor, a central stem or hub carried by and movable With the disk, and projecting at one side of the handle, a seat itted to the stem, and having opposite jaws or flanges, and a Wrench detachably held between the jaws or flanges of the seat.

4L. In a ratchet-Wrench, l[he combination of a handle having a4 ratchet-disk, and dogs therefor, a central stem or hub carried by and movable With the disk, projecting at one side of the handle, and provided With an angular portion and a screw-threaded portion, a

Wren chhaving an angular opening detachablyiitting the angular' portion of the stem, and a nut fitted to the threaded portion of the stem and bearing against the Wrench.

5. In a ratchet-Wrench, the combination of a handle, having a ratchetdisk, and dogs therefor, a central hub or stem carried by and movable With the disk,"projecting at one side of the handle, and having ashoulder, an anguiar portion, and a screw-threaded portion, a seat having an angular opening detaehably fitting the angular portion of the stem, and opposite jaws 'or flanges, a Wrench deta chably fitted between the jaws or flanges of the seat, and having an angular' opening receiving the angular portion of the stem, and a nut fitted to the threaded portion `of the stem and bearing against the Wrench.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two Witnesses.

WILLIAM M. ARTHUR.
